As active members of the American Ornithologists' Union, we are only too glad to encourage the study of birds and aid the beginner, but unless some steps be taken against this useless egg collecting, the extermination of some at least of our birds will soon be effected.
We ask your earnest consideration of these points, and trust you will aid us by your influence and example in advancing true ornithology, and in discouraging the waste of bird-life occasioned by this "fad" of egg collecting.
